Check lens quality
Legitimate sunglasses should bear markings such as the product name, color, diameter, quality grade, manufacturer details (name and address), trademark, and warning statements.
Check lens color
Sunglasses come in a variety of lens colors, with gray, brown, and amber being the most common. Consumers can choose a color that complements their skin tone, hair color, and personal style.
Light transmission
Light transmission is a key indicator of lens quality. Generally, high-quality sunglasses should have a light transmission rate of over 80% to ensure clear vision in sunlight. Consumers can assess quality by observing the lens's light transmission.
Check performance
When purchasing sunglasses, consumers should consider lens impact resistance and heat resistance. Generally, materials like polycarbonate and acrylic offer superior impact resistance, while glass and certain specialized resins provide better heat resistance.
Check frame material
In general, metal frames are considered premium, non-metal frames tend to be lightweight, and plastic or synthetic frames are more budget-friendly. Additionally, consider whether the frame size and shape suit your face and nose bridge, and ensure the weight and comfort level are appropriate.
